SFU & MCU Mode? Do I Use Both?

In addition to the MCU mode, our sharp developers recently introduced the SFU mode. But what are the MCU and SFU modes and why I am using both? Answers can be found here ✅

eyeson’s technology is based on the MCU mode. This means that the streams from all participants get mixed in a central entity which sends out a single stream towards each participant. Therefore, flawless and stable video and audio quality are assured.

Due to this technology, the bandwidth stays always stable at approximately 2 Mbits. It does not matter how many participants take part in the group video call since the streams get anyway mixed into one single stream. As eyeson possesses a patent on it, it is the only video call provider which is able to deliver such top-notch technology 🆕

Still, many of our customers make 1:1 video calls. This is the reason why our team decided to introduce the SFU mode. With this special mode, video processing is simply accelerated, especially for a 1:1 call.

So how does the SFU mode work?

Well, your stream is directly sent via the eyeson cloud service ☁ to your video call participant and reverse without additional processing of the video layout. However, this mode is only activated when 2 people have a video call. If a third party joins, the mode switches automatically to the MCU mode. From 3 on, it makes sense to use the MCU mode again to keep the premium video and audio quality 🔝 Though do not get confused- in our tool we call it fusion mode 😎

Here you can watch how both modes work:

So how differs eyeson’s 1:1 call from other providers?

eyeson still processes the 1:1 video calls in the cloud service. As a result, you can use all eyeson features like screen sharing, file presentation, recording, GIF reactions, snapshots, adjustable video layout and Quick Join. Moreover, you can broadcast your 1:1 call on Youtube and Facebook. The SFU mode combines the advantages of the server side processing of the MCU mode and API accessibility while offering a powerful optimized 1:1 video call 👥

During the video call, you can see an icon on the bottom right-hand corner. When the fusion mode (MCU) is activated it starts moving. Just have a look by yourself and log in to youraccount.
